DOUBLE home page showing up

I install OG module and set access control and all other stuffs ok.

Now I enable "My Groups" block as a block appearing on the right side.
I click on 'configure' and set 'maximunm number of itemsto show' to 3

I create / subscribe to more than 3 blocks so that the link 'more' appears in the side block.

I am logged in and click on more :
Clicking on 'more' under 'My Groups' as side block gives 'You are not authorized to access this page.'
Along with this I get DOUBLE home page showing up without any understandable reason !!!
Please see this : http://drupal.org/files/issues/drupal-double-homepage.GIF
Please help !! I have submitted this as bug report and forum post and searched all forum and specific module pages without any response.

I guess anyone can reproduce this on localhost or actual site. Some workaround is urgently needed.
I shall be highly obliged for any help.
